I recently got my column changed in EW. I was getting thud thud sound on moving the steering left and right.The service manager pointed the issue with column, most probably UJ joint (his words).He applied for EW and on the day when the column was already opened another service adviser told me that there was not need to change the column as this sound is there in all Lineas and he demonstrated me in a new Linea parked.And after the change as expected the sound was still there.i asked him what was the need. He consoled me "But still k sir now ur car has a new column now for free, good for u".I had no words happy to get something new for free but still some doubts. Now after the column change the steering is little off its not centralized that couldn't be observed after the column change . A alinement guy told me that the centering issue is very minute and it cant be adjusted from toe and it has to done from column.I tried getting it centralized once from TASS and once from outside but the issue still there. Can settings in column effect he steering centralization, if some body can explain me.
